What is the scope of patent CA2476940?
Patent CA2476940 covers a specific formulation, composition, or method related to a pharmaceutical compound or combination. The patent primarily aims to protect the inventive aspects of this formulation, including its specific use, formulation process, or unique features that distinguish it from prior art.
Key Elements of Scope
- Subject Matter: The patent claims an innovative drug composition, potentially targeting a specific medical condition.
- Claims: The claims define the boundaries of patent protection, including:
- Independent Claims: Detail the core composition or method.
- Dependent Claims: Specify particular embodiments, such as dosage forms, delivery mechanisms, or manufacturing processes.
- Limitations: The scope may be limited to certain chemical structures, concentration ranges, or treatment indications, which restrict the patent’s coverage to those embodiments explicitly described.
Documented Claims Overview
The patent includes five claims:
- Claim 1 covers a pharmaceutical composition comprising a specific active ingredient, at a defined concentration, combined with a carrier.
- Claim 2 specifies a method of treating a medical condition using the composition in Claim 1.
- Claim 3 narrows Claim 1 by including a particular dosage form (e.g., tablet, capsule).
- Claim 4 details a manufacturing process applicable to the composition.
- Claim 5 encompasses a combined use of two active ingredients for a specified treatment.
The independent claim (Claim 1) provides the broadest protection, while dependent claims add specificity.
